Detailed Description

This class represents lattice values for constants.

Implement a low-level type suitable for MachineInstr level instruction selection.

\macro LLVM_ENABLE_EXCEPTIONS Whether LLVM is built with exception support.

Lightweight arrays that are backed by an arbitrary BinaryStream.

This file contains the declaration of the GlobalIFunc class, which represents a single indirect function in the IR.

FIXME: This is basically just for bringup, this can be made a lot more rich in the future.

Indirect function uses ELF symbol type extension to mark that the address of a declaration should be resolved at runtime by calling a resolver function.

This file provides two different array implementations.

VarStreamArray - Arrays of variable length records.  The user specifies
  an Extractor type that can extract a record from a given offset and
  return the number of bytes consumed by the record.

FixedStreamArray - Arrays of fixed length records.  This is similar in
  spirit to ArrayRef<T>, but since it is backed by a BinaryStream, the
  elements of the array need not be laid out in contiguous memory. 

For a type attached to a MachineInstr, we only care about 2 details: total size and the number of vector lanes (if any). Accordingly, there are 4 possible valid type-kinds:

• sN for scalars and aggregates
• <N x sM> for vectors, which must have at least 2 elements.
• pN for pointers

Other information required for correct selection is expected to be carried by the opcode, or non-type flags. For example the distinction between G_ADD and G_FADD for int/float or fast-math flags.

AliasResult

enum llvm::AliasResult : uint8_t

The possible results of an alias query.

These results are always computed between two MemoryLocation objects as a query to some alias analysis.

Note that these are unscoped enumerations because we would like to support implicitly testing a result for the existence of any possible aliasing with a conversion to bool, but an "enum class" doesn't support this. The canonical names from the literature are suffixed and unique anyways, and so they serve as global constants in LLVM for these results.

See docs/AliasAnalysis.html for more information on the specific meanings of these values.

Enumerator
NoAlias	The two locations do not alias at all. This value is arranged to convert to false, while all other values convert to true. This allows a boolean context to convert the result to a binary flag indicating whether there is the possibility of aliasing.
MayAlias	The two locations may or may not alias. This is the least precise result.
PartialAlias	The two locations alias, but only due to a partial overlap.
MustAlias	The two locations precisely alias each other.

FunctionModRefBehavior

enum llvm::FunctionModRefBehavior

Summary of how a function affects memory in the program.

Loads from constant globals are not considered memory accesses for this interface. Also, functions may freely modify stack space local to their invocation without having to report it through these interfaces.

Enumerator
FMRB_DoesNotAccessMemory	This function does not perform any non-local loads or stores to memory. This property corresponds to the GCC 'const' attribute. This property corresponds to the LLVM IR 'readnone' attribute. This property corresponds to the IntrNoMem LLVM intrinsic flag.
FMRB_OnlyReadsArgumentPointees	The only memory references in this function (if it has any) are non-volatile loads from objects pointed to by its pointer-typed arguments, with arbitrary offsets. This property corresponds to the IntrReadArgMem LLVM intrinsic flag.
FMRB_OnlyAccessesArgumentPointees	The only memory references in this function (if it has any) are non-volatile loads and stores from objects pointed to by its pointer-typed arguments, with arbitrary offsets. This property corresponds to the IntrArgMemOnly LLVM intrinsic flag.
FMRB_OnlyAccessesInaccessibleMem	The only memory references in this function (if it has any) are references of memory that is otherwise inaccessible via LLVM IR. This property corresponds to the LLVM IR inaccessiblememonly attribute.
FMRB_OnlyAccessesInaccessibleOrArgMem	The function may perform non-volatile loads and stores of objects pointed to by its pointer-typed arguments, with arbitrary offsets, and it may also perform loads and stores of memory that is otherwise inaccessible via LLVM IR. This property corresponds to the LLVM IR inaccessiblemem_or_argmemonly attribute.
FMRB_OnlyReadsMemory	This function does not perform any non-local stores or volatile loads, but may read from any memory location. This property corresponds to the GCC 'pure' attribute. This property corresponds to the LLVM IR 'readonly' attribute. This property corresponds to the IntrReadMem LLVM intrinsic flag.
FMRB_DoesNotReadMemory
FMRB_UnknownModRefBehavior	This indicates that the function could not be classified into one of the behaviors above.

RemapFlags

enum llvm::RemapFlags

These are flags that the value mapping APIs allow.

Enumerator
RF_None
RF_NoModuleLevelChanges	If this flag is set, the remapper knows that only local values within a function (such as an instruction or argument) are mapped, not global values like functions and global metadata.
RF_IgnoreMissingLocals	If this flag is set, the remapper ignores missing function-local entries (Argument, Instruction, BasicBlock) that are not in the value map. If it is unset, it aborts if an operand is asked to be remapped which doesn't exist in the mapping. There are no such assertions in MapValue(), whose results are almost unchanged by this flag. This flag mainly changes the assertion behaviour in RemapInstruction(). Since an Instruction's metadata operands (even that point to SSA values) aren't guaranteed to be dominated by their definitions, MapMetadata will return "!{}" instead of "null" for LocalAsMetadata instances whose SSA values are unmapped when this flag is set. Otherwise, MapValue() completely ignores this flag. MapMetadata() always ignores this flag.
RF_MoveDistinctMDs	Instruct the remapper to move distinct metadata instead of duplicating it when there are module-level changes.
RF_NullMapMissingGlobalValues	Any global values not in value map are mapped to null instead of mapping to self. Illegal if RF_IgnoreMissingLocals is also set.

CloneAndPruneFunctionInto()

		SmallVectorImpl< ReturnInst * > &	Returns,
		const char *	NameSuffix = "",
		ClonedCodeInfo *	CodeInfo = nullptr,

	)

This works exactly like CloneFunctionInto, except that it does some simple constant prop and DCE on the fly.

The effect of this is to copy significantly less code in cases where (for example) a function call with constant arguments is inlined, and those constant arguments cause a significant amount of code in the callee to be dead. Since this doesn't produce an exactly copy of the input, it can't be used for things like CloneFunction or CloneModule.

If ModuleLevelChanges is false, VMap contains no non-identity GlobalValue mappings.

		ValueToValueMapTy &	VMap,
		const Twine &	NameSuffix = "",

		ClonedCodeInfo *	CodeInfo = nullptr,
		DebugInfoFinder *	DIFinder = nullptr
	)

Return a copy of the specified basic block, but without embedding the block into a particular function.

See comments in Cloning.h.

The block returned is an exact copy of the specified basic block, without any remapping having been performed. Because of this, this is only suitable for applications where the basic block will be inserted into the same function that it was cloned from (loop unrolling would use this, for example).

Also, note that this function makes a direct copy of the basic block, and can thus produce illegal LLVM code. In particular, it will copy any PHI nodes from the original block, even though there are no predecessors for the newly cloned block (thus, phi nodes will have to be updated). Also, this block will branch to the old successors of the original block: these successors will have to have any PHI nodes updated to account for the new incoming edges.

The correlation between instructions in the source and result basic blocks is recorded in the VMap map.

If you have a particular suffix you'd like to use to add to any cloned names, specify it as the optional third parameter.

If you would like the basic block to be auto-inserted into the end of a function, you can specify it as the optional fourth parameter.

If you would like to collect additional information about the cloned function, you can specify a ClonedCodeInfo object with the optional fifth parameter.

CloneFunction()

Function * llvm::CloneFunction	(	Function *	F,

Return a copy of the specified function and add it to that function's module.

Also, any references specified in the VMap are changed to refer to their mapped value instead of the original one. If any of the arguments to the function are in the VMap, the arguments are deleted from the resultant function.

Note that if NewFunc already has basic blocks, the ones cloned into it will be added to the end of the function. This function fills in a list of return instructions, and can optionally remap types and/or append the specified suffix to all values cloned.

Compute all the import and export for every module using the Index.

ModuleToDefinedGVSummaries contains for each Module a map (GUID -> Summary) for every global defined in the module.

ImportLists will be populated with an entry for every Module we are importing into. This entry is itself a map that can be passed to FunctionImporter::importFunctions() above (see description there).

ExportLists contains for each Module the set of globals (GUID) that will be imported by another module, or referenced by such a function. I.e. this is the set of globals that need to be promoted/renamed appropriately.

computeMinimumValueSizes()

MapVector< Instruction *, uint64_t > llvm::computeMinimumValueSizes	(	ArrayRef< BasicBlock * >	Blocks,
		DemandedBits &	DB,
		const TargetTransformInfo *	TTI = nullptr
	)

Compute a map of integer instructions to their minimum legal type size.

C semantics force sub-int-sized values (e.g. i8, i16) to be promoted to int type (e.g. i32) whenever arithmetic is performed on them.

For targets with native i8 or i16 operations, usually InstCombine can shrink the arithmetic type down again. However InstCombine refuses to create illegal types, so for targets without i8 or i16 registers, the lengthening and shrinking remains.

Most SIMD ISAs (e.g. NEON) however support vectors of i8 or i16 even when their scalar equivalents do not, so during vectorization it is important to remove these lengthens and truncates when deciding the profitability of vectorization.

This function analyzes the given range of instructions and determines the minimum type size each can be converted to. It attempts to remove or minimize type size changes across each def-use chain, so for example in the following code:

%1 = load i8, i8* %2 = add i8 %1, 2 %3 = load i16, i16* %4 = zext i8 %2 to i32 %5 = zext i16 %3 to i32 %6 = add i32 %4, %5 %7 = trunc i32 %6 to i16

Instruction %6 must be done at least in i16, so computeMinimumValueSizes will return: {%1: 16, %2: 16, %3: 16, %4: 16, %5: 16, %6: 16, %7: 16}.

If the optional TargetTransformInfo is provided, this function tries harder to do less work by only looking at illegal types.

ComputeMultiple()

bool llvm::ComputeMultiple	(	Value *	V,
		unsigned	Base,
		Value *&	Multiple,
		bool	LookThroughSExt = false,
		unsigned	Depth = 0
	)

This function computes the integer multiple of Base that equals V.

If successful, it returns true and returns the multiple in Multiple. If unsuccessful, it returns false. Also, if V can be simplified to an integer, then the simplified V is returned in Val. Look through sext only if LookThroughSExt=true.

If successful, it returns true and returns the multiple in Multiple. If unsuccessful, it returns false. It looks through SExt instructions only if LookThroughSExt is true.

		bool	UseInstrInfo = true
	)

Return the number of times the sign bit of the register is replicated into the other bits.

We know that at least 1 bit is always equal to the sign bit (itself), but other cases can give us information. For example, immediately after an "ashr X, 2", we know that the top 3 bits are all equal to each other, so we return 3. For vectors, return the number of sign bits for the vector element with the mininum number of known sign bits.

containsIrreducibleCFG()

template<class NodeT , class RPOTraversalT , class LoopInfoT , class GT = GraphTraits<NodeT>>

bool llvm::containsIrreducibleCFG	(	RPOTraversalT &	RPOTraversal,
		const LoopInfoT &	LI
	)

Return true if the control flow in RPOTraversal is irreducible.

This is a generic implementation to detect CFG irreducibility based on loop info analysis. It can be used for any kind of CFG (Loop, MachineLoop, Function, MachineFunction, etc.) by providing an RPO traversal (RPOTraversal) and the loop info analysis (LI) of the CFG. This utility function is only recommended when loop info analysis is available. If loop info analysis isn't available, please, don't compute it explicitly for this purpose. There are more efficient ways to detect CFG irreducibility that don't require recomputing loop info analysis (e.g., T1/T2 or Tarjan's algorithm).

Requirements: 1) GraphTraits must be implemented for NodeT type. It is used to access NodeT successors. target CFG with begin()/end() iterator interfaces. 3) LI must be a valid LoopInfoBase that contains up-to-date loop analysis information of the CFG.

This algorithm uses the information about reducible loop back-edges already computed in LI. When a back-edge is found during the RPO traversal, the algorithm checks whether the back-edge is one of the reducible back-edges in loop info. If it isn't, the CFG is irreducible. For example, for the CFG below (canonical irreducible graph) loop info won't contain any loop, so the algorithm will return that the CFG is irreducible when checking the B <- -> C back-edge.

(A->B, A->C, B->C, C->B, C->D) A / \ B<- ->C | D

Check whether the edge (Src, Dst) is a reducible loop backedge according to LI. I.e., check if there exists a loop that contains Src and where Dst is the loop header.

createInterleaveMask()

Constant * llvm::createInterleaveMask	(	IRBuilder<> &	Builder,

Create an interleave shuffle mask.

This function creates a shuffle mask for interleaving NumVecs vectors of vectorization factor VF into a single wide vector. The mask is of the form:

<0, VF, VF * 2, ..., VF * (NumVecs - 1), 1, VF + 1, VF * 2 + 1, ...>

For example, the mask for VF = 4 and NumVecs = 2 is:

<0, 4, 1, 5, 2, 6, 3, 7>.

Create a mask with replicated elements.

This function creates a shuffle mask for replicating each of the VF elements in a vector ReplicationFactor times. It can be used to transform a mask of VF elements into a mask of VF * ReplicationFactor elements used by a predicated interleaved-group of loads/stores whose Interleaved-factor == ReplicationFactor.

For example, the mask for ReplicationFactor=3 and VF=4 is:

Uses ExpandReminder with a 32bit Rem which makes it useful for targets with little or no support for less than 32 bit arithmetic.

Replace Rem with generated code.

Uses the above routines and extends the inputs/truncates the outputs to operate in 32 bits; that is, these routines are good for targets that have no or very little suppport for smaller than 32 bit integer arithmetic.

Replace Rem with emulation code.

filterDeadComdatFunctions()

void llvm::filterDeadComdatFunctions	(	Module &	M,

Filter out potentially dead comdat functions where other entries keep the entire comdat group alive.

This is designed for cases where functions appear to become dead but remain alive due to other live entries in their comdat group.

The DeadComdatFunctions container should only have pointers to Functions which are members of a comdat group and are believed to be dead.

After this routine finishes, the only remaining Functions in DeadComdatFunctions are those where every member of the comdat is listed and thus removing them is safe (provided all are removed).

findAllocaForValue()

FindAvailableLoadedValue()

Value * llvm::FindAvailableLoadedValue	(	LoadInst *	Load,
		BasicBlock *	ScanBB,
		BasicBlock::iterator &	ScanFrom,
		unsigned	MaxInstsToScan = DefMaxInstsToScan,
		AliasAnalysis *	AA = nullptr,
		bool *	IsLoadCSE = nullptr,
		unsigned *	NumScanedInst = nullptr
	)

Scan backwards to see if we have the value of the given load available locally within a small number of instructions.

You can use this function to scan across multiple blocks: after you call this function, if ScanFrom points at the beginning of the block, it's safe to continue scanning the predecessors.

Note that performing load CSE requires special care to make sure the metadata is set appropriately. In particular, aliasing metadata needs to be merged. (This doesn't matter for store-to-load forwarding because the only relevant load gets deleted.)

Parameters

	Load	The load we want to replace.
	ScanBB	The basic block to scan.
[in,out]	ScanFrom	The location to start scanning from. When this function returns, it points at the last instruction scanned.
	MaxInstsToScan	The maximum number of instructions to scan. If this is zero, the whole block will be scanned.
	AA	Optional pointer to alias analysis, to make the scan more precise.
[out]	IsLoadCSE	Whether the returned value is a load from the same location in memory, as opposed to the value operand of a store.

Returns

The found value, or nullptr if no value is found.

You can use this function to scan across multiple blocks: after you call this function, if ScanFrom points at the beginning of the block, it's safe to continue scanning the predecessors.

Parameters

	Ptr	The pointer we want the load and store to originate from.
	AccessTy	The access type of the pointer.
	AtLeastAtomic	Are we looking for at-least an atomic load/store ? In case it is false, we can return an atomic or non-atomic load or store. In case it is true, we need to return an atomic load or store.
	ScanBB	The basic block to scan.
[in,out]	ScanFrom	The location to start scanning from. When this function returns, it points at the last instruction scanned.
	MaxInstsToScan	The maximum number of instructions to scan. If this is zero, the whole block will be scanned.

formLCSSA()

bool llvm::formLCSSA	(	Loop &	L,

Put loop into LCSSA form.

Looks at all instructions in the loop which have uses outside of the current loop. For each, an LCSSA PHI node is inserted and the uses outside the loop are rewritten to use this node. Sub-loops must be in LCSSA form already.

LoopInfo and DominatorTree are required and preserved.

If ScalarEvolution is passed in, it will be preserved.

Returns true if any modifications are made to the loop.

Ensures LCSSA form for every instruction from the Worklist in the scope of innermost containing loop.

For every instruction from the worklist, check to see if it has any uses that are outside the current loop.

For the given instruction which have uses outside of the loop, an LCSSA PHI node is inserted and the uses outside the loop are rewritten to use this node.

LoopInfo and DominatorTree are required and, since the routine makes no changes to CFG, preserved.

Returns true if any modifications are made.

Make MDOperand transparent for hashing.

Note that overloading hash_value() as follows:

size_t hash_value(const MDOperand &X) { return hash_value(X.get()); }

does not cause MDOperand to be transparent. In particular, a bare pointer doesn't get hashed before it's combined, whereas MDOperand would.

Assign a complexity or rank value to LLVM Values.

We do not have to consider the commuted variants of these patterns because canonicalization based on complexity guarantees the above ordering.

This routine maps IR values to various complexity ranks: 0 -> undef 1 -> Constants 2 -> Other non-instructions 3 -> Arguments 4 -> Cast and (f)neg/not instructions 5 -> Other instructions

This method is similar to GetUnderlyingObject except that it can look through phi and select instructions and return multiple objects.

If LoopInfo is passed, loop phis are further analyzed. If a pointer accesses different objects in each iteration, we don't look through the phi node. E.g. consider this loop nest:

int **A; for (i) for (j) { A[i][j] = A[i-1][j] * B[j] }

This is transformed by Load-PRE to stash away A[i] for the next iteration of the outer loop:

Curr = A[0]; // Prev_0 for (i: 1..N) { Prev = Curr; // Prev = PHI (Prev_0, Curr) Curr = A[i]; for (j: 0..N) { Curr[j] = Prev[j] * B[j] } }

Since A[i] and A[i-1] are independent pointers, getUnderlyingObjects should not assume that Curr and Prev share the same underlying object thus it shouldn't look through the phi above.

getUniqueModuleId()

Produce a unique identifier for this module by taking the MD5 sum of the names of the module's strong external symbols that are not comdat members.

This identifier is normally guaranteed to be unique, or the program would fail to link due to multiply defined symbols.

If the module has no strong external symbols (such a module may still have a semantic effect if it performs global initialization), we cannot produce a unique identifier for this module, so we return the empty string.

template<typename T , typename RecoveryFtor , typename... HandlerTs>

Expected< T > llvm::handleExpected	(	Expected< T >	ValOrErr,

Handle any errors (if present) in an Expected<T>, then try a recovery path.

If the incoming value is a success value it is returned unmodified. If it is a failure value then it the contained error is passed to handleErrors. If handleErrors is able to handle the error then the RecoveryPath functor is called to supply the final result. If handleErrors is not able to handle all errors then the unhandled errors are returned.

This utility enables the follow pattern:

enum FooStrategy { Aggressive, Conservative };
Expected<Foo> foo(FooStrategy S);
 
auto ResultOrErr =
  handleExpected(
    foo(Aggressive),
    []() { return foo(Conservative); },
    [](AggressiveStrategyError&) {

llvm::InlineResult llvm::InlineFunction	(	CallBase *	CB,
		InlineFunctionInfo &	IFI,
		AAResults *	CalleeAAR = nullptr,
		bool	InsertLifetime = true
	)

This function inlines the called function into the basic block of the caller.

This returns false if it is not possible to inline this call. The program is still in a well defined state if this occurs though.

Note that this only does one level of inlining. For example, if the instruction 'call B' is inlined, and 'B' calls 'C', then the call to 'C' now exists in the instruction stream. Similarly this will inline a recursive function by one level.

Note that while this routine is allowed to cleanup and optimize the inlined code to minimize the actual inserted code, it must not delete code in the caller as users of this routine may have pointers to instructions in the caller that need to remain stable.

If ForwardVarArgsTo is passed, inlining a function with varargs is allowed and all varargs at the callsite will be passed to any calls to ForwardVarArgsTo. The caller of InlineFunction has to make sure any varargs are only used by ForwardVarArgsTo.

install_bad_alloc_error_handler()

void llvm::install_bad_alloc_error_handler	(	fatal_error_handler_t	handler,
		void *	user_data = nullptr
	)

Installs a new bad alloc error handler that should be used whenever a bad alloc error, e.g.

failing malloc/calloc, is encountered by LLVM.

The user can install a bad alloc handler, in order to define the behavior in case of failing allocations, e.g. throwing an exception. Note that this handler must not trigger any additional allocations itself.

If no error handler is installed the default is to print the error message to stderr, and call exit(1). If an error handler is installed then it is the handler's responsibility to log the message, it will no longer be printed to stderr. If the error handler returns, then exit(1) will be called.

Parameters

user_data

- An argument which will be passed to the installed error handler.

install_fatal_error_handler()

void llvm::install_fatal_error_handler	(	fatal_error_handler_t	handler,

	)

install_fatal_error_handler - Installs a new error handler to be used whenever a serious (non-recoverable) error is encountered by LLVM.

If no error handler is installed the default is to print the error message to stderr, and call exit(1). If an error handler is installed then it is the handler's responsibility to log the message, it will no longer be printed to stderr. If the error handler returns, then exit(1) will be called.

It is dangerous to naively use an error handler which throws an exception. Even though some applications desire to gracefully recover from arbitrary faults, blindly throwing exceptions through unfamiliar code isn't a way to achieve this.

Parameters

user_data

- An argument which will be passed to the install error handler.

Determine whether there is a path from From to To within a single function. Returns false only if we can prove that once 'From' has been executed then 'To' can not be executed. Conservatively returns true.

This function is linear with respect to the number of blocks in the CFG, walking down successors from From to reach To, with a fixed threshold. Using DT or LI allows us to answer more quickly. LI reduces the cost of an entire loop of any number of blocks to be the same as the cost of a single block. DT reduces the cost by allowing the search to terminate when we find a block that dominates the block containing 'To'. DT is most useful on branchy code but not loops, and LI is most useful on code with loops but does not help on branchy code outside loops.

isSafeToSpeculativelyExecute()

bool llvm::isSafeToSpeculativelyExecute	(	const Value *	V,
		const Instruction *	CtxI = nullptr,
		const DominatorTree *	DT = nullptr
	)

Return true if the instruction does not have any effects besides calculating the result and does not have undefined behavior.

This method never returns true for an instruction that returns true for mayHaveSideEffects; however, this method also does some other checks in addition. It checks for undefined behavior, like dividing by zero or loading from an invalid pointer (but not for undefined results, like a shift with a shift amount larger than the width of the result). It checks for malloc and alloca because speculatively executing them might cause a memory leak. It also returns false for instructions related to control flow, specifically terminators and PHI nodes.

If the CtxI is specified this method performs context-sensitive analysis and returns true if it is safe to execute the instruction immediately before the CtxI.

If the CtxI is NOT specified this method only looks at the instruction itself and its operands, so if this method returns true, it is safe to move the instruction as long as the correct dominance relationships for the operands and users hold.

This method can return true for instructions that read memory; for such instructions, moving them may change the resulting value.

Create a new loop identifier for a loop created from a loop transformation.

Parameters

OrigLoopID	The loop ID of the loop before the transformation.
FollowupAttrs	List of attribute names that contain attributes to be added to the new loop ID.
InheritOptionsAttrsPrefix	Selects which attributes should be inherited from the original loop. The following values are considered: nullptr : Inherit all attributes from OrigLoopID. "" : Do not inherit any attribute from OrigLoopID; only use those specified by a followup attribute. "<prefix>": Inherit all attributes except those which start with <prefix>; commonly used to remove metadata for the applied transformation.
AlwaysNew	If true, do not try to reuse OrigLoopID and never return None.

Returns

The loop ID for the after-transformation loop. The following values can be returned: None : No followup attribute was found; it is up to the transformation to choose attributes that make sense. OrigLoopID: The original identifier can be reused. nullptr : The new loop has no attributes. MDNode* : A new unique loop identifier.

makeGuardControlFlowExplicit()

void llvm::makeGuardControlFlowExplicit	(	Function *	DeoptIntrinsic,

Splits control flow at point of Guard, replacing it with explicit branch by the condition of guard's first argument.

The taken branch then goes to the block that contains Guard's successors, and the non-taken branch goes to a newly-created deopt block that contains a sole call of the deoptimize function DeoptIntrinsic.

	)

Create a new LoopID after the loop has been transformed.

This can be used when no follow-up loop attributes are defined (llvm::makeFollowupLoopID returning None) to stop transformations to be applied again.

Parameters

Context	The LLVMContext in which to create the new LoopID.
OrigLoopID	The original LoopID; can be nullptr if the original loop has no LoopID.
RemovePrefixes	Remove all loop attributes that have these prefixes. Use to remove metadata of the transformation that has been applied.
AddAttrs	Add these loop attributes to the new LoopID.

Returns

A new LoopID that can be applied using Loop::setLoopID().

Pattern match integer [SU]MIN, [SU]MAX and ABS idioms, returning the kind and providing the out parameter results if we successfully match.

For ABS/NABS, LHS will be set to the input to the abs idiom. RHS will be the negation instruction from the idiom.

If CastOp is not nullptr, also match MIN/MAX idioms where the type does not match that of the original select. If this is the case, the cast operation (one of Trunc,SExt,Zext) that must be done to transform the type of LHS and RHS into the type of V is returned in CastOp.

For example: %1 = icmp slt i32 a, i32 4 %2 = sext i32 a to i64 %3 = select i1 %1, i64 %2, i64 4

-> LHS = a, RHS = i32 4, *CastOp = Instruction::SExt

Peel off the first PeelCount iterations of loop L.

Note that this does not peel them off as a single straight-line block. Rather, each iteration is peeled off separately, and needs to check the exit condition. For loops that dynamically execute PeelCount iterations or less this provides a benefit, since the peeled off iterations, which account for the bulk of dynamic execution, can be further simplified by scalar optimizations.

Point debug users of From to To or salvage them.

Use this function only when replacing all uses of From with To, with a guarantee that From is going to be deleted.

Follow these rules to prevent use-before-def of To: . If To is a linked Instruction, set DomPoint to To. . If To is an unlinked Instruction, set DomPoint to the Instruction To will be inserted after. . If To is not an Instruction (e.g a Constant), the choice of DomPoint is arbitrary. Pick From for simplicity.

If a debug user cannot be preserved without reordering variable updates or introducing a use-before-def, it is either salvaged (salvageDebugInfo) or deleted. Returns true if any debug users were updated.

This method introduces at least one new basic block into the function and moves some of the predecessors of BB to be predecessors of the new block.

The new predecessors are indicated by the Preds array. The new block is given a suffix of 'Suffix'. Returns new basic block to which predecessors from Preds are now pointing.

If BB is a landingpad block then additional basicblock might be introduced. It will have Suffix+".split_lp". See SplitLandingPadPredecessors for more details on this case.

This currently updates the LLVM IR, DominatorTree, LoopInfo, and LCCSA but no other analyses. In particular, it does not preserve LoopSimplify (because it's complicated to handle the case where one of the edges being split is an exit of a loop with other exits).

SplitCriticalEdge() [4/4]

BasicBlock * llvm::SplitCriticalEdge	(	Instruction *	TI,
		unsigned	SuccNum,

If this edge is a critical edge, insert a new node to split the critical edge.

This will update the analyses passed in through the option struct. This returns the new block if the edge was split, null otherwise.

If MergeIdenticalEdges in the options struct is true (not the default), all edges from TI to the specified successor will be merged into the same critical edge block. This is most commonly interesting with switch instructions, which may have many edges to any one destination. This ensures that all edges to that dest go to one block instead of each going to a different block, but isn't the standard definition of a "critical edge".

It is invalid to call this function on a critical edge that starts at an IndirectBrInst. Splitting these edges will almost always create an invalid program because the address of the new block won't be the one that is jumped to.

This method transforms the landing pad, OrigBB, by introducing two new basic blocks into the function.

One of those new basic blocks gets the predecessors listed in Preds. The other basic block gets the remaining predecessors of OrigBB. The landingpad instruction OrigBB is clone into both of the new basic blocks. The new blocks are given the suffixes 'Suffix1' and 'Suffix2', and are returned in the NewBBs vector.

This currently updates the LLVM IR, DominatorTree, LoopInfo, and LCCSA but no other analyses. In particular, it does not preserve LoopSimplify (because it's complicated to handle the case where one of the edges being split is an exit of a loop with other exits).

UnrollLoop()

	)

Unroll the given loop by Count.

The loop must be in LCSSA form. Unrolling can only fail when the loop's latch block is not terminated by a conditional branch instruction. However, if the trip count (and multiple) are not known, loop unrolling will mostly produce more code that is no faster.

TripCount is the upper bound of the iteration on which control exits LatchBlock. Control may exit the loop prior to TripCount iterations either via an early branch in other loop block or via LatchBlock terminator. This is relaxed from the general definition of trip count which is the number of times the loop header executes. Note that UnrollLoop assumes that the loop counter test is in LatchBlock in order to remove unnecesssary instances of the test. If control can exit the loop from the LatchBlock's terminator prior to TripCount iterations, flag PreserveCondBr needs to be set.

PreserveCondBr indicates whether the conditional branch of the LatchBlock needs to be preserved. It is needed when we use trip count upper bound to fully unroll the loop. If PreserveOnlyFirst is also set then only the first conditional branch needs to be preserved.

Similarly, TripMultiple divides the number of times that the LatchBlock may execute without exiting the loop.

If AllowRuntime is true then UnrollLoop will consider unrolling loops that have a runtime (i.e. not compile time constant) trip count. Unrolling these loops require a unroll "prologue" that runs "RuntimeTripCount % Count" iterations before branching into the unrolled loop. UnrollLoop will not runtime-unroll the loop if computing RuntimeTripCount will be expensive and AllowExpensiveTripCount is false.

If we want to perform PGO-based loop peeling, PeelCount is set to the number of iterations we want to peel off.

The LoopInfo Analysis that is passed will be kept consistent.

This utility preserves LoopInfo. It will also preserve ScalarEvolution and DominatorTree if they are non-null.

If RemainderLoop is non-null, it will receive the remainder loop (if required and not fully unrolled).

Insert code in the prolog/epilog code when unrolling a loop with a run-time trip-count.

This method assumes that the loop unroll factor is total number of loop bodies in the loop after unrolling. (Some folks refer to the unroll factor as the number of extra copies added). We assume also that the loop unroll factor is a power-of-two. So, after unrolling the loop, the number of loop bodies executed is 2, 4, 8, etc. Note - LLVM converts the if-then-sequence to a switch instruction in SimplifyCFG.cpp. Then, the backend decides how code for the switch instruction is generated.

Prolog case extraiters = tripcount % loopfactor if (extraiters == 0) jump Loop: else jump Prol: Prol: LoopBody; extraiters -= 1 // Omitted if unroll factor is 2. if (extraiters != 0) jump Prol: // Omitted if unroll factor is 2. if (tripcount < loopfactor) jump End: Loop: ... End:

Epilog case extraiters = tripcount % loopfactor if (tripcount < loopfactor) jump LoopExit: unroll_iters = tripcount - extraiters Loop: LoopBody; (executes unroll_iter times); unroll_iter -= 1 if (unroll_iter != 0) jump Loop: LoopExit: if (extraiters == 0) jump EpilExit: Epil: LoopBody; (executes extraiters times) extraiters -= 1 // Omitted if unroll factor is 2. if (extraiters != 0) jump Epil: // Omitted if unroll factor is 2.
